Product Features:
Julari PVA is a white granular water-soluble synthetic resin. The chemical name is Polyvinyl alcohol, or PVA for short. The main properties of PVA are determined by the degree of resolution and degree of polymerization of the molecules constituting the resin. And has the following properties:
(1) Water solubility: soluble in water.
(2) Viscosity of aqueous solution: The viscosity of an aqueous solution of PVA is varied depending on the temperature of the polymerization degree. It is lower than other water-soluble polymers.
(3) Film-forming property: An aqueous solution of PVA is easily formed into a film, and the film is superior to physical properties such as tensile strength and abrasion resistance.
(4) Hygroscopicity: The film of PVA is lower than hygroscopicity, and the change with humidity is smaller than other water-soluble polymers.
(5) Resistance to chemicals and oils: PVA has strong resistance. In addition, it is superior to oil resistance.
